Leak-free guaranteed - No other protein shaker on the market is designed to endure the wear and tear that a PerfectShaker does. Our proprietary design has been optimized to ensure that no matter how the cup is used, it will not leak. Actionrod technology - During the blending process, the agitator and rod combine to form a high-performance piston, colliding with high momentum in the opposite direction of the mixture. This rapid collision builds momentum and the explosive impact results in instant emulsification and perfectly blended drinks every time. May the force be with you - Bring out your inner superhero during your Duraplex shatter resistant plastic - Not all workout shaker bottles are made the same. The quality of the plastic used and its overall density play a key role in how shatter resistant it is. PerfectShaker bottles use a specialized blend of polymers that ensure maximum shock absorption and elasticity. BPA free, dishwasher safe with extralast ink - Our protein shaker cups are 100% BPA free for the safest supplement consumption. Our Extralast Ink ensures that the design on your shaker cup stays pristine wash after wash.Colour Name: Purple
